Be it! known that l, @soARf A. Piiomsnn, a citizen of the' United States, .and a resident=` of the citj7 of4 New York, borough of the Bronx, county and-State off' New York, have invented certain new and useful- Improve'- nients in `Roofing Tiles, of which the following` is a full, clear, and exact description.

Among the principal objects which the present invention has in view are: to avoid breakage of the tile in service and in handling; to forni runways for. water; to provide means incorporated inthe structure for aligning the tile; to conceal the junction of the tiles in the separate courses; to kavoid leakage; and to provide a means for anchoring` the tile in service relation.

Drawings.

Figure l is a top plan view of a fragment ot a roofing tile, constructed and arranged in accordance with the present invention;

Figure 2 is a cross section thereof, the

section being taken on the line 9,?-2 in Figure l; y

Figure 3 is a sectional view, the section being taken as on the line 3-3 vin Figure l. and showing in conjunction therewith by dotted lines the relation of an adjacent tile; f

Figure i is a perspective view of Ia tile constructed and arranged in accordance with.

the present invention.

Description.

Tile, `when shaped as shown in the draw. ings, are constructed from cement concrete,

which is molded to form lengthwise grooves' 9, 10 and l1. The grooves' 9 andlO form runways for moisture falling on or accuinu` lated on a roof covered by said tile. The grooves l1 are for aligning theadjacent tile. Each tile is provided at one endwith the grooves 1l, and at the opposite end, o'r

As seen best in Figures 3 and 4, the tiler is hollow beneath to form pairs of aligned recesses 14%?,-y one'onI each side of the planes beneath' the tile' and between the samel and' the 'sheathing onwhich it is usuallvinounted.

Intermediate the ends of the tile cross ridges l5 are provided to interrupt the continuity of the recesses i4, wherebyA to form the pairs of the latter, as above stated.y Piercing the cross ridges l5 are perforations 16, designed toreceive atying member suoli as the wire which is passed aroundy the sheathing or convenient element of the structure for securing the tile in place.

From the Jforegoing it will be seen that a roof constructed and arranged in accord,-v

ance"l with the present invention is light and strong, and so arranged that sidedrifting of water such as deposited on the roofby rain, is prevented, and that in consequence the water is` evenly delivered throughout the roof to the drainage gutter with'` which the sainel is furnished.
